Mainly GABAergic interneurons (see Markram H, Toledo-Rodriguez M, Wang Y, et al. 2004 Interneurons of the neocortical inhibitory system. Nat Rev Neurosci 5:793-807; Ascoli GA et al. 2008 Petilla terminology: Nomenclature of features of GABAergic interneurons of the cerebral cortex. Nat Rev Neurosci 9:557-568; DeFelipe J et al. 2013 New insights into the classification and nomenclature of cortical GABAergic interneurons. Nat Rev Neurosci 14:202-216); the current subdivision is based on preferred postsynaptic region.

Functional subdivision of the Isocortex as described by Mesulam M-M (1985 Patterns in behavioral neuroanatomy. In: Mesulam M-M, ed: Principles of Behavioral Neurology. Davis, Philadelphia, PN, pp 1-70). The Granular isocortex ranges from Hypergranular through Granular to Dysgranular.

Here, the Isocortical neurons are added, in part following and modifying TH terms. They are subdivided into Pyramidal neurons (Projection, Commissural nand Association eurons) and Excitatory and Inhibitory interneurons. In general, Small pyramidal neurons are found in Layer II and give rise to ipsilateral Corticocortical projections. Medium-sized pyramidal neurons are found in Layer III and give rise to Commissural projections. The Large pyramidal neurons in Layer V give rise to the Corticofugal projections (Mountcastle VB 1998 The Cerebral Cortex. Harvard University Press, Cambridge, MA).
